Ground Cover rose plant named &#39;Noalesa&#39;

ABSTRACT

A new and distinct variety for Ground Cover Rose plant is provided which forms substantially continuously throughout the season attractive long-lasting bright yellow blossoms. The blossoms open on a reliable bases and retain their attractiveness upon aging. The new variety exhibits a compact, spreading and overhanging growth habit that renders it suitable for growing as attractive ornamentation in the landscape. The foilage is glossy and dark green and contrasts well with the bright yellow blossoms. The blossom petals detach cleanly as the blossoms mature. The new variety propagates well by the use of cuttings, and by budding and grafting. Excellent resistance to Blackspot, Powdery Mildew, and Rust is exhibited.

SUMMARY OF THE INVENTION

[0001] Ground Cover rose plants are known and are being used toadvantage in an increasing number of landscape plans and home gardens.However, there remains a need for additional varieties of Ground Coverroses with the demand being the greatest for those having highlyattractive blossoms in combination with good disease resistance.

[0002] The new variety of Rosa hybrida Ground Cover rose plant of thepresent invention was created at Gütersloh, Germany, by artificialpollination wherein two parents were crossed which previously had beenstudied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) was the‘Korimro’ variety (non-patented in the United States). Such ‘Korimro’variety possesses light pink to near white single blossoms and ismarketed under the IMMENSEE trademark. The male parent (i.e., the pollenparent) was an unnamed seedling maintained by Noack Rosen at Gütersloh,Germany (non-patented in the United States). The parentage of the newvariety can be summarized as follows:

‘Korimro’×Unnamed Seedling

[0003] The seeds resulting from the above pollination were sown andsmall plants were obtained which physically and biologically differ fromeach other. Selective study resulted in the identification of a singleplant to the new variety.

[0004] It is found that the new variety of Ground Cover rose plantpossesses the following combination of characteristics:

[0005] (a) forms attractive bright yellow blossoms,

[0006] (b) young plants exhibit an upright growth habit that becomesspreading, dense, and compact with maturity,

[0007] (c) forms attractive dark green glossy foliage that contrastswell with the bright yellow blossoms,

[0008] (d) exhibits excellent disease resistance with respect toBlackspot, Powdery Mildew, and Rust, and

[0009] (e) is particularly well suited for growing as attractiveornamentation in the landscape.

[0010] The new variety meets the needs of the horticultural industry andcan be grown to advantage as attractive ornamentation in parks, gardens,public areas, and residential landscapes.

[0011] The new variety of the present invention beginning in 1994 hasbeen asexually reproduced by the rooting of cuttings, by budding, and bygrafting. Such asexual reproduction as performed at Gütersloh, Germany,has demonstrated that the characteristics of the new variety are firmlyfixed and stable and are strictly transmissible from one generation toanother.

[0012] The new variety has been named the ‘Noalesa’, and recently hasbeen marketed under the JACOBS KRÖNUNG trademark.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0013] The accompanying photographs show as nearly true as it isreasonably possible to make the same, in color illustrations of thischaracter, typical specimens of the new variety while growing in thelandscape. The illustrated rose plants were photographed during July,1996, while growing in the field at Gütersloh, Germany. Such plants werebudded approximately one and one-half years earlier.

[0014]FIG. 1 illustrates the overall appearance of typical plants of thenew variety while bearing a profusion of blossoms in various stages ofopening.

[0015]FIG. 2 illustrates a closer view of typical blossoms, buds, andfoliage of the new variety wherein the bright yellow blossoms are shownto contrast nicely with the glossy dark green foliage.

DETAILED DESCRIPTION

[0016] The chart used in the identification of the colors is that of TheRoyal Horticultural Society (R.H.S. Colour Chart) of London, England.Color terminology in common terms sometimes is included as an aid to thereader. Such terminology is to be accorded its customary dictionarysignificance. The description is based on the observation of specimensof the new variety while growing outdoors during July at Gütersloh,Germany.
